At each stage of the project, we strive to minimise disruption to your life - and keep you fully informed of progress. Our transparent costings and clear explanations of exactly what needs to happen at each stage gives you a sense of control and confidence throughout the process.

How we quote

We have built up a fantastic reputation for our unparalleled detail when it comes to build estimates.

We break down exactly where the money is being spent to give you far greater control from the outset. Transparency is key to our approach. This is a big investment. You need to feel 100% comfortable with how and where your money’s being spent.

2 hour personal consultation

We will visit you to gather information to discuss design options for your home and the relevant planning and building regulations requirements.

We will then provide a comprehensive fixed price quotation so you know exactly where your money is being spent and a sketch of the proposed conversion/extension where applicable. We can also arrange for you to view a similar project in your area, to give you an opportunity to see the standard of work and to help you realise the potential for your own home.


Design phase

We’ve been doing this for 16 years so we have developed excellent relationships with a number of architects with whom we have a proven record of working.

But you might already have a trusted architect or the drawings themselves. We’re very adaptable and work around whatever you’re more comfortable with.

Start Plan Process

A small initial payment is needed to confirm your booking and to get the planning process started. Payment for this can be made by cheque, credit/debit card or by bankers’ draft. We then allocate your project to one of our designers and give you a proposed start date. Due to the structure of our payment schedule, which is quite unique within the industry, payments are only taken in arrears of work, and therefore no further payments are required until work has begun.

Full Measured Survey

One of our in-house designers visits your property to undertake a full measured survey. This takes approximately one and a half hours. Metos Design & Build then draw up the relevant architectural plans. It normally takes 2-4 weeks to draw up the plans and to get them registered with the local council.

Architectural Plans

Metos Design & Build send you a copy of the architectural plans for your approval. A copy is then sent to the local council in conjunction with your planning/lawful development application. It takes approximately eight weeks for the council to decide the application.

Party Wall Surveyor

During the planning application period you are required to serve party wall notice(s) on your neighbour(s), to which they must consent prior to the commencement of the work. We will put you in touch with a party wall surveyor who will supply you with the notice(s) free of charge. We strongly recommend you serve these notices at your earliest opportunity in order to ensure works starts promptly after planning consent has been obtained.

Planning Approval

A few weeks before the build starts, Metos Design & Build will apply for building regulations on your behalf. Once planning approval has been obtained construction normally commences within 2-4 weeks.

Working with you

The week before work commences, you will have a “pre-start” meeting with your consultant and the site foreman. The site foreman will be managing the team constructing your development. This meeting is an opportunity to fine-tune any details of your impending project. The site foreman will run you through the build process, explaining how they intend to tackle the project, the best channels of communication and how they will protect your home and minimise disruption to your family.

The Build

The building team arrive on the agreed start date and construction begins. Prior to this, preparation of the site along with the protection of key areas will have already taken place; skips will have been delivered and scaffolding erected where appropriate.

Temporary kitchens come as standard on our jobs. Our team is also known for its friendliness and ability to fit in with the needs of family life. At the end of every working day the work area is left scrupulously clean.

Check-up Visits

During the construction stage of your project your dedicated consultant will visit your site 2-3 times a week to ensure works are progressing according to schedule. If you need to contact us at any stage of your project, we have a fully functioning office, open Mon-Fri 9am-5pm. so there will always be someone available to take your call.


You can expect construction work to last approximately 5-7 weeks for a loft, 7-10 weeks for an extension and 3-6 months for a basement. Upon completion of your project you will receive a ten year guarantee for the works, your building regulations certificate, a copy of your planning approval and most importantly some precious space.
